it’s a very cool thing indeed that you can use in a studio or improv session and you can get unexpected results by using any audio source and not just single cycle waves, but the thing is that it’s dependent on routing, so for people who for example use multiple kits/patterns they would have to make this routing consistent and permanent both for using same individual outs and removing the voices from main outs, this is not replacing a second lfo you can save with the kit/pattern and when you turn the machine on it just works without the extra routing steps.
also, if you do use different audio waveforms you’d need to go into the CV menu every time to re-learn the audio, making it a bit useless for a live set unless you use the same audio source.
but for experimentation/studio recording this feature is very unique, the best thing is it’s a macro lfo with up to 4 destination across all voices and fx, very cool.
also people with DAW and dc coupled audio interfaces can use CV tools and internal lfos to get even better lfos, or even use something like VCV Rack to generate lfos, this way you don’t have to sacrifice voices.
